MILWAUKEE — A Milwaukee officer involved in the stun gun arrest of Bucks' player Sterling Brown has been fired because of social media posts mocking the incident, the city's police chief said Thursday.

Police Chief Alfonso Morales said the firing decision was not tied to anything Erik Andrade did when Brown was arrested, but explained that the social media posts compromised the officer's ability to testify in other cases. Morales spoke about the case at a Marquette University event.
